The options-flow "Debug write" panel could only ever do one write to one
href per pass -- not enough for the issue #300 wall oven, whose board
discards settings writes while idle and only keeps them once a cycle is
already running. Finding what starts a cycle needs an ordered sequence of
writes across resources, with real settle delays between them, and a way
to check afterward whether anything actually held.
- coordinator.py: async_raw_write_sequence owns a whole ordered sequence
under one _session_lock hold (so a poll can't interleave mid-sequence),
with per-step settle and an optional delayed verify_after re-read done
outside the lock. async_raw_write is now a one-item wrapper over it, so
tests/test_coordinator_raw_write.py keeps passing unmodified. Also adds
async_raw_read, a live GET bypassing the cache -- staleness is exactly
what makes revert-testing unreliable.
- services.py (new): the two HA services. Device-target resolution scans
loaded coordinators' MAIN/subdevice identifiers and requires exactly one
match, so an area/label target can't silently fan a raw write out across
several appliances. Canonical->actual href translation happens here, not
in the coordinator, which stays subdevice-agnostic.
- services.yaml (new): selectors/descriptions for both services, inline
per HA's custom-integration support -- keeps translations/en.json's
mirror test (test_translations.py) green without touching all 6
languages for a services block. New exception keys (write caps, device
target resolution) still went into translations/*.json's existing
exceptions section, mirrored across all 6 languages.
- __init__.py: adds async_setup to register the services once, process-wide.
- config_flow.py: the debug panel's async_step_debug_edit now calls
write_resource instead of coord.async_raw_write directly, so there is
exactly one code path that performs a raw write.
- README.md: new Part 5 documenting both services, with a worked
write_resource example; points the capability-gap section at them.
tests/test_services.py (new): sequencing/ordering, settle timing, changed
vs. held (the reverted case is issue #300's own symptom), exactly-one-
device resolution, subdevice href translation, validation caps, and the
options-flow panel end to end through the service.
Same feature name as the WindFree already modeled via climate.py's preset
system on regular AC boards, but a genuinely different wire mechanism --
this device's fields live on their own dedicated hrefs with no evidenced
coupling to hvac_mode, unlike the Comode_Nano token's real gating rules on
legacy boards. Recorded in-line so this doesn't come up as a 'why isn't
this a preset' question again without the answer already being there.
PR #316 (fork stale by several months, most of its ~2200-line diff was drift
against main rather than real changes) proposed device support for the
Samsung System Fresh Air Ventilator (ACA-KR-TP2-21-AN9000). Extracted what
holds up, adapted to this project's conventions, and left out what doesn't:
Extracted:
- ventilation_mode select on CLIMATE's own href, gated via
_is_ventilation_mode_device so it can only ever bind on a device whose
entire supportedModes set is Purification/Ventilation/SmartVentilation --
verified against every real AC fixture in the corpus to confirm it can't
false-positive on an actual air conditioner's climate card.
- WINDFREE / WINDSLEEP switches on their own dedicated hrefs.
- A CO2 sensor on AIR_QUALITY, matching air_monitor.SENSORS' already-bound
device_class='carbon_dioxide'/unit='ppm' descriptor for the same field
shape rather than guessing fresh.
- HEPA_FILTER / DEVICE_ACTIVE reuse from air_purifier.py.
- Removing /airlevelcheck/vs/0 from _AC_IGNORED and binding
air_purifier.AIR_LEVEL_CHECK in its place: the PR's claim that this
project's old "scheduler plumbing" description was wrong turned out to
be independently verifiable against two of our own existing fixtures
(airconditioner_cac and airconditioner_tp1x_da_ac_rac_01011 both already
carry real, populated periodicSensingActivationState/autoExeState
values), so this benefits existing users, not just the one new device.
Left out:
- Unit/device_class ('ug/m3', pm10/pm25/pm1) on the existing dust/
fine_dust/super_fine_dust sensors, sourced from an unverified third-party
screenshot description. air_monitor.py already has an explicit, reasoned
rejection of this exact mapping for the exact same three fields:
Samsung's PM10/PM2.5 convention doesn't confirm where a third tier or a
PM1 reading fits, and a wrong guess mislabels the reading forever.
- A standalone common.POWER switch -- contradicts this registry's own
documented design (power is deliberately the climate entity's job) and
would affect every AC user, not just this device.
- Promoting wind/swing to independent selects for every AC user -- a UX
opinion, not a coverage necessity, and out of scope for this device's
own support.
- A model-name diagnostic sensor -- /information/vs/0 is already covered
via the global ignore list, so this wasn't closing an actual gap.
No raw diagnostics dump for this model was ever attached to PR #316, so
there's no fixture for it here (fabricating one would violate this
project's fixture-integrity rule) -- see
tests/test_airconditioner_ventilation_windfree.py's module docstring.
resolve()/for_device_by_model() return DeviceRegistry | None; four new
test files used reg.capabilities/reg.pattern_capabilities without
narrowing away None first. Add the same 'assert reg is not None' idiom
test_dehumidifier_tp1x_dhm01001_capabilities.py already uses.
Verified against a clean venv running the exact CI commands (ruff format
--check, ruff check, ty check, pytest) rather than trusting a stale local
venv that had picked up a mismatched python3.11/3.13 site-packages split.
- Fix a real bug: airconditioner.SOUND_MODE had no exists_fn, so on
boards (issue #319's FAC) that never report a live 'mode' value,
entity.py's default field-presence gate silently kept the select from
ever registering in HA -- while adapter.flatten() (what the golden/tests
read) has no such gate, so the tests passed while documenting behavior
the opposite of what shipped. Gate on supportedModes' presence instead.
- Add airconditioner.MDS_ABSENCE_CLEAN for the CAC-class board's
/mds/absenceclean/vs/0 -- byte-identical shape to issue #319's
/csi/absenceclean/vs/0, confirmed rather than guessed, closing one more
of that board's documented coverage-gap hrefs.
- Add missing translation state labels (all 6 languages) for
edge_lighting_mode/edge_lighting_color/indicator_light_mode's raw device
codes, so they render as real words instead of a raw '3000K' -> '3000 K'
fallback.
- Fix an orphaned comment above SOUND_MODE that actually described the
unrelated DISPLAY reuse, and correct two inaccurate rationale comments:
the sound/voice ignore reason claimed a distinction from SOUND_MODE that
this same dump contradicts, and the /csi/* ignore block's 'same
reasoning as air_purifier.COVERAGE' precedent only actually covers 1 of
its 5 hrefs.
- Correct the false 'no board-token match' claim in the FAC test file and
golden-regression docstring -- 'FAC' is a real _BOARD_TOKEN_TO_KEY entry
(for_device_by_model alone already resolves this board); add a test
that actually exercises that path, which nothing previously did despite
the docstring's claim.
- Drop a tautological burner-slot test that only re-asserted what the
golden regression test already covers via the same code path.
Six System A/C cassette units on the same board test_airconditioner_cac.py
already documented as having an incomplete coverage gap gave real dump
evidence for two of its remaining unbound hrefs:
- /edgelighting/vs/0: an accent-light strip with on/off, a Smart/High/Low
mode, and a Kelvin color-temperature select (3000K/4000K/6500K), all read
from the device's own live supported-value lists.
- /light/stateful/vs/0: a second, distinct light resource with its own
on/off and Smart/Low/High mode -- not to be confused with EDGE_LIGHTING
or DISPLAY_LIGHT's ambient mood light.
convenientMode/operatingOption on /edgelighting/vs/0 stay unexposed: present
on every dump but no evidence of what either actually controls.
Only three hrefs remain in test_airconditioner_cac.py's documented gap now
(absence-clean, sound-optimization, smart-sensing-cooling).
/diagnosis/vs/0 was the dump's only unbound href, now covered via
dishwasher.DIAGNOSIS (same shape already reused by airconditioner.py).
This steam-oven-class board's /mode/vs/0 options[] carries no UpperLamp_
token at all, unlike the NV7000BS-class board LAMP was proven against --
LAMP had no exists_fn, so it registered anyway, always read Off, and any
write to it was a no-op the device had no reason to honor. Gives it the
same options-token exists_fn gate issue #183 already added to
fast_preheat/natural_steam/energy_saving/cooktop_on_alert.
/alarms/vs/0 and /kidslock/vs/0 were the dump's two unbound hrefs -- both
are the exact shapes common.UNIVERSAL already models elsewhere
(common.ALARMS, common.KIDS_LOCK_VS_FALLBACK), picked individually rather
than pulling in all of UNIVERSAL to match this registry's existing
hand-picked-common style.
The six-vs-three burner count the reporter originally asked about is
expected behavior (the board's own /mode/vs/0 options genuinely advertise
six OperationState slots on hardware with three physical burners, with no
per-device signal to tell real slots from phantom ones) -- already
explained on the issue; this commit is scoped to the coverage warning.
/filter/airdustfilter/vs/0 was the dump's only unbound href -- this board's
internal deodorizing filter, same filterUsage/filterStatus field pair as
common.WATER_FILTER, but filterUsage here is already a 0-100 percentage
with no filterCapacity to divide by (confirmed by filterStatus=="wash" at
filterUsage=="100"). Uses air_-prefixed keys so a fridge with both a
water and an air filter gets two distinct entities.
This board routes purely via /oic/d's oic.d.airconditioner type (no
board-token match) and reports several resources the sibling
TP1X_DA-AC-CAC-01001 board (issue #191) left as a documented gap:
- /display/vs/0, /settings/sound/output/vs/0, /settings/sound/volume/vs/0
now reuse air_purifier.py's identical-shape capabilities instead of
duplicating them.
- /settings/sound/mode/vs/0 gets a new airconditioner.SOUND_MODE reading
the live supportedModes field, sharing laundry.py's existing
voice/tone/mute translation catalog since the value vocabulary matches.
- /csi/absenceclean/vs/0 and /csi/energysaving/vs/0 are new, genuinely
useful controls (absence auto-clean toggle, energy-saving mode select
plus its state/operatingStatus diagnostics).
- /dnd/autosleep/vs/0, /outdoorsharing/vs/0, /lifestyle/survey/vs/0,
/settings/sound/voice/vs/0 and /csi/information/vs/0 are ignored as
plumbing/unconfirmed data with no user-actionable state.
Also fixes a latent bug in air_purifier.SOUND_VOLUME: boards that report
minLevel/resolution but no maxLevel (this one) would have produced a
min=0/max=0 number entity instead of self-gating off.
Updates test_airconditioner_cac.py's documented coverage gap now that
sound_mode/sound_output/sound_volume are covered there too.
Review question on #304: a bare Comode_Off written over Comode_Sleep/Sleep_4
read back as Comode_Off/Sleep_0 at +8s and +38s, so the preset path cannot
leave a stale duration for the next nano selection to read as a running timer.
One map is not enough to judge by: with only OptionCode present, every
eoc-gated rule reads None, and None means the board does not publish the map
rather than that the feature is absent. artik051_dongle_fac_18k is exactly that
board and lost WindFree in every mode. Requiring both also keeps these bit
positions inside the family they were documented for -- the FAC and CAC dumps
carry only the older map, with values small enough that RAC positions read as
zeros.
Also from review: an unknown HVAC mode falls back the same way, Comfort is
spelled like the identical Speed rule, the unreachable AIComfort branch is
gone, the Cool code comes from the unit's own supportedModes, DlightCool gains
its catalog entry, and the Single User claim is dropped -- the app's own Single
User command sends Comode_Smart, so there is no distinct token to write.
coordinator is explicitly typed as LocalThingsCoordinator here, so ty
correctly sees _session's declared type (DtlsCoapSession | None) and
flags assigning a FakeObserveSession to it. The fixture's own
_connect_session replacement does the same swap without tripping ty,
but only because its self parameter is unannotated -- ty has nothing to
check the assignment against there. Deliberate here (this is the whole
point of the test: substitute a stand-in session), so silenced rather
than restructured; ty's --add-ignore confirmed the comment syntax
(ty: ignore[...], not the mypy-style type: ignore[...] used elsewhere
in this suite, which ty doesn't appear to honor for this rule).
A second review of the observe-mode phase split (previous commit) found
two real regressions it introduced, both in the same failure family it
was built to close:
- async_send_command's failed-retry branch closed the session, then
raised without downgrading observe mode -- the downgrade only ran on
the retry's success path. A retry that also fails still leaves the
session dead, so mode was left claiming "Push" on a session that no
longer exists, same as the bug this whole fix targets. Moved the
downgrade to run right after the close, unconditionally on how the
retry goes.
- _attempt_observe_mode's stale-session abandon (the identity-check
branch added in the previous commit) didn't flag a resubscribe. A
session swap discovered there means a fresh, never-tried session now
exists, but _last_observe_attempt_ts was already stamped for the
now-abandoned attempt -- so that new session sat unsubscribed for up
to _RECOVERY_RETRY_S (600s) instead of being retried on the next
cycle. Now sets _resubscribe_due, same as the two reconnect paths do.
Also closes two test-coverage gaps the same review surfaced by mutation
testing: no test asserted the lock actually holds during the subscribe
burst (only that it's released for the wait), and no test distinguished
the max() in _maybe_retry_observe_mode's throttle from using
_last_observe_attempt_ts alone -- both mutations left the full suite
green. Added one test for each, plus extended two existing tests for the
bug fixes above; all four confirmed via mutation testing (revert the
fix, watch the new/extended test fail; restore it, watch it pass).
One finding from the same review is intentionally left open: async_close
is the one self._session writer that doesn't take _session_lock, so a
close racing _attempt_observe_mode isn't covered by today's identity
check. This is pre-existing (the lock didn't cover any of
_attempt_observe_mode before this branch's earlier commits either), not
a regression from this branch's work, and is a shutdown/unload-path
question rather than the write-vs-observe-mode race this branch set out
to fix.
The command-retry fix (issue #294) added a self._close_session() call to
async_send_command that isn't synchronized against _attempt_observe_mode,
which reads self._session and subscribes to it without holding
_session_lock. A write's retry racing an in-flight subscribe attempt
could tear down the session mid-subscribe -- or worse, land the close
*after* the attempt's grace wait already succeeded, letting it commit
observe mode against a session that's already gone: mode claims "Push"
forever, with nothing left to notice the underlying socket is dead.
Split ObserveManager.try_enter_observe_mode into four pieces
(subscribe_hrefs / await_observe_notifies / enter_observe_mode /
abandon_observe_attempt), keeping try_enter_observe_mode as a thin
wrapper so its direct callers in test_observe.py are unaffected.
_attempt_observe_mode now holds _session_lock only for the subscribe
burst (each send is fire-and-forget, not a network round trip) and
re-checks self._session is sess under the lock right before committing
-- sess keeps the old session object alive, so identity can't be
recycled onto a new one, which is what makes the check sufficient
without a separate generation counter. The wait itself stays lock-free,
so a command write is never blocked behind it.
Two more bugs the same investigation turned up, fixed in the same pass
since they're direct consequences of the design above:
- async_send_command's own successful reconnect didn't downgrade observe
mode the way the poll path's reconnect already does, leaving the same
stale-commit problem reachable with zero concurrency at all -- just a
write's retry succeeding while mode was observe. Replaced the poll
path's local just_downgraded_from_observe with an instance flag both
reconnect sites set, so either one triggers an immediate resubscribe.
- _maybe_retry_observe_mode's 600s throttle gated solely on
last_mode_change_ts, which _set_mode only stamps on an actual
transition -- a device that never succeeds at observe mode leaves that
timestamp stuck at construction time, so the throttle opens once and
never closes again, re-attempting on every single poll cycle instead
of every 600s. Now gates on the more recent of that timestamp and a
new _last_observe_attempt_ts, stamped on every attempt regardless of
outcome.
An Opus review of the three prior commits on this branch (PR #306)
turned up two real defects and a documentation/test gap, all fixed
here:
- async_send_command's retry (issue #294) armed the write-settle
window before the retry existed, so the reconnect pause plus a
second PUT could eat into the time meant for the confirming poll,
reviving the revert-then-reapply symptom the window was sized to
prevent (issue #9). Re-arm it after a successful retry lands.
- test_send_command_reconnects_and_retries_after_socket_closed relied
on the observe-session fixture's no-op _close_session, so
self._session never actually went None and _do_put's reconnect
guard was never exercised -- the test passed even with that guard
deleted. Now overrides _close_session/_connect_session to actually
drop and rebuild the session, and asserts the reconnect happened.
- async_send_command's docstring still said "Fire-and-forget", which
stopped being true the moment it started retrying and raising.
Also trimmed the three comment blocks the review flagged as
reproducing their commit messages verbatim, per CONTRIBUTING.md's
comment-style rules.
One review finding is not addressed here and needs a decision: the
new _close_session() call in the command-retry path isn't
synchronized against _attempt_observe_mode, which touches the session
without _session_lock. A write's reconnect can race an in-flight
observe-mode subscribe attempt and tear down the session it's using.
Fixing it properly means broadening lock scope around observe-mode
entry, which risks blocking a write behind an up to ~15s subscribe
grace period -- a tradeoff not made unilaterally here.
A second finding (dropping the old .strip()'s per-line whitespace
handling in _normalize_pem) did not reproduce against a real
certificate/key, only against the test suite's placeholder PEM body,
so it's left as-is.
async_send_command's _do_put caught any exception, logged it, and
returned -- no reconnect, no retry, no error the user could see. A
command landing on a session Samsung's firmware closed between polls
(the same 'known device behavior' _async_update_data already
reconnects around) was silently lost, with nothing to do about it but
a manual reload of the device (issue #294).
Mirror the poll path's own recovery: on failure, close the dead
session, pause, and retry the PUT once against a freshly reconnected
one. If that also fails, raise a HomeAssistantError instead of just
logging, so the user gets a visible error rather than a command that
quietly did nothing. The retry runs under the same session lock the
poll path uses, so a write landing mid-reconnect can't race a
concurrent poll cycle rebuilding the same session.
When a poll fails and the immediate reconnect retry fails too,
_async_update_data returned the last-known snapshot as a degraded
success (issue #254) without ever touching observe mode. That's fine
for the data itself, but the connection-mode sensor reads straight
from self._observe.mode, and only the *successful* reconnect branch
ever changed it -- so a device that drops off the network entirely
(air-gapped, powered off, Wi-Fi down) left that sensor reporting
"Push" forever, hours after the session was actually dead (issue
#287).
Downgrade to poll mode on the failure branch too, without attempting
an immediate resubscribe: the reconnect that would normally justify
one just proved there's no live session to subscribe on. Recovery
still happens on its own once the device is reachable again, via the
existing poll-mode retry timer (_maybe_retry_observe_mode).
A PEM pasted from a text editor can carry bytes cryptography's parser
refuses outright: a UTF-8 BOM some Windows editors silently prepend,
CRLF line endings, and a stray blank line a paste can introduce
between the header/body/footer. None of those are meaningful in PEM,
but any of them surfaces as an opaque InvalidHeader with no hint of
what's wrong -- which is why the same certificate pasted from
Command Prompt's `type` (no BOM, no stray blank lines) loads fine
while the same file opened in an editor and copied doesn't (issue
#291).
Normalize at the point the pasted blob is first captured, not just
before minting the leaf cert: the same string is stored in the config
entry and reused to re-mint the leaf on a future reconfigure, so a
raw copy would keep failing every time it's read back, not just on
the first attempt.
The fixed list of six was offered in every mode on every legacy board. The
appliance publishes what it has as two bit maps in /mode/vs/0's options, and its
own app gates each comfort mode on a bit plus the current mode; this transcribes
that logic. WindFree also needs the mode written before it in Auto, which is
measured rather than assumed.
Sleep_<n> written on its own is answered 2.04 Changed and then discarded, so
the Number wrote nothing at all. Nano wind shares the same Comode_ slot, which
is why writing the nano preset over a running timer silently changed its
duration, and why the two sleep codes the board reports had to become presets:
a preset_mode outside preset_modes is not a state HA allows.
The Sleep_ token was published as if its value were hours. It is not: the
appliance's own app pairs a duration picker with the values it puts on the wire,
one to one, and the pairing is half hours.
0:00 0:30 1:00 1:30 2:00 2:30 3:00 4:00 5:00 ... 12:00
0 1 2 3 4 5 6 8 10 ... 24
So the entity capped at 12 hours actually set six, every value asked for was
halved on the appliance, and twelve hours -- the app's own maximum, stated in its
help text -- could not be reached at all. The reading is halved and the write
doubled, and the step drops to 0.5 because that is the resolution the picker
offers.
Half-hour steps are what the app offers below three hours; above that it offers
whole hours only, so a half hour up there is untested rather than known-bad. A
Number cannot change step part-way, and turning this into a Select of the app's
sixteen values would change the entity's domain on every unit that already has
one, so the step stays 0.5 throughout and the comment says why.
The descriptor's own comment used to admit the upper bound was a guess ("only 0
has been observed on hardware"). The guess of 12 was right; the unit it was
expressed in was not.
test_every_language_mirrors_the_english_catalog is right to fail on this: a key
present only in English falls back silently at runtime, which reads as a
half-finished translation rather than a missing one.
Also fills in the same key for ko.json, which the original fix predates:
Korean's translation catalog was added after this branch was cut and never
picked up filter_time_reset either.
FilterCleanAlarm_Clear, through the same single-token options merge as every
other setting on /mode/vs/0. Measured on an ARTIK051_KRAC_18K: 2.04 Changed and
FilterTime_95 (9 h 30 min) -> FilterTime_0, still zero on a fresh DTLS session
and on every poll after; none of the other 17 tokens moved and the alarm
entries stayed Deleted.
The counter has had no reset until now, and the descriptor said so: two earlier
rounds against live hardware failed, and the conclusion drawn from them was
that the reset had to be cloud-only. That conclusion was wrong, and the way it
was reached is the interesting part -- it came from diffing every resource the
appliance reports before and after pressing reset in Samsung's app, which
showed only the counter zeroing and the alarm clearing. A trigger token cannot
show up in such a diff, because a trigger is never stored. The appliance's own
app sends this token and skips the write when the counter is already zero.
Both failures stay in the comment, because they say what this is not: writing
FilterTime_0 (the value is not writable -- 5595 -> 5595 after 69 s, 1925 ->
1925 after 65 s, two units, opposite power states), and POSTing the cloud
capability's command name to /actions/vs/0 (real name, wrong transport).
Gated on the FilterTime_ token, so it appears only where there is a counter to
reset; newer boards report filter usage through their own resource and would
need a different mechanism.
ko.json (PR #283) was written against an older en.json and never picked up
the ten keys two later PRs added: the AI Purify sensing entities
(switch.periodic_air_sensing, switch.periodic_sensing_skip_status,
number.sensing_interval, select.sensing_mode + its three states,
time.sensing_skip_start/end) and button.auto_clean_stop. Merging main
into this branch surfaced the gap via
test_every_language_mirrors_the_english_catalog.
Translated the missing entries, matching the terminology and phrasing
ko.json already uses for adjacent keys (e.g. periodic_air_sensing's
existing binary_sensor entry, auto_clean's "자동 청소"), and kept "AI
Purify" as the untranslated brand name the same way cs/es/it/nl do.
ko.json's topology now matches en.json's exactly; full suite (1213
tests), ruff, and ty all pass.
CONTRIBUTING.md gains a "Code comments" section: comment the why not
the what, keep it to a sentence or two with a pointer to the load-bearing
evidence, don't re-derive a sibling's already-documented reasoning, and
move failed-attempt investigation logs out of inline comments.
Applied that policy across the codebase: condensed sprawling module
docstrings, per-entity essays, and multi-paragraph rationale blocks down
to their load-bearing conclusions, while preserving the actual "why"
(issue numbers, calibration evidence, gotchas, don't-guess rationale).
No functional code changed — verified via diff review, ruff, ty, and the
full pytest suite (1211 passed).
One inline investigation log (the AC filter-reset "tried and failed"
notes) moved to docs/investigations/ac-filter-reset.md rather than being
deleted, per the new guideline on where that kind of record belongs.
Three tokens describe the drying cycle these boards run after cooling, and the
switch only covered the first. AutocleanProgress_ is how far a running cycle
has got, and StopAutoClean_ is a channel for ending one early -- its presence
is what says the appliance accepts that at all, which is how the appliance's
own app gates its stop button. Both tokens are reported by the ARTIK051_KRAC_18K
that issue #136 was about, and by every KRAC fixture here.
The percentage scale is the app's own: it renders the token into a
`<progress max="100">` with a "{{value}}%" label beside it. An idle unit reports
1 rather than 0 -- the same floor the laundry firmware's progressPercentage sits
at when Ready -- so 0-vs-1 is not a reliable "is it running" test, and the
button is deliberately not gated on it.
The sensor shares AUTO_CLEAN's catalog entry the way auto_clean_legacy already
shares the switch's: same figure, different board generation, distinct key so
nothing collides if a board ever reported both.
Stacked on #289 (this branch is cut from it) -- rebase or merge that first.
The frozenset was a parallel structure for a per-row fact, and the comment
above the tuple already described it as a fourth column -- so the comment
promised the right shape and the code did something else. Fixed to the shape
the comment described: _AIR_QUALITY_SENSORS carries state_class per row and
the comprehension unpacks it, with _RECORDED_AIR_QUALITY and its duplicated
rationale block deleted.
air_monitor imports the same rows and now unpacks four, but discards the
fourth. That board (issue #210) has stamped all five readings as
`measurement` since it was added; consuming the column would silently drop
long-term statistics for Odor and CleanLevel on shipped devices, which is a
behaviour change this branch has no evidence to make. The grade/concentration
split stays scoped to the air purifier.
test_shared_sensor_tuple_keeps_its_three_column_shape asserted the premise
this replaces -- that widening the tuple breaks air_monitor's import -- so it
is replaced rather than renumbered: one test that the rows carry their own
state_class, and one that air_monitor still imports and still stamps all five.
Dropping native_min to 0 fixed the read range and quietly opened a write:
native_min governs what the user can enter, not just what renders, so 0
became enterable and would have gone out as periodicSensingInterval "0".
Nothing establishes what that does to this board -- both fixtures report 600,
the app's smallest choice is 10 min, and 60 s is the lowest value confirmed
accepted. The two precedents leaned on differ in exactly the way that matters:
oven.cook_time and operational.delay_start_hours sit at a zero floor under a
value where 0 is a real setting ("no timer", "no delay").
One minute is also the resolution this board reports results at.
lastSensingTime lands on an exact minute on every sample from the AVT-WW-TP1
and A-VTWW-TP2 boards -- both fixtures, plus eleven consecutive live readings
-- where the TP1X/AC/hood boards report arbitrary seconds. A sub-minute
interval is unobservable here whether or not the board honours it.
So native_min goes to 1 rather than 0, and the read rounds up instead of to
nearest so a sub-minute reading renders as 1 rather than falling below the
entity's own floor. The write still refuses anything under a minute -- a None
return, the silent no-op range_hood._lamp_level_write uses for a level the
device didn't advertise -- since native_min only guards the UI path, not a
service call.
